The wavelengths of visible light are: Violet: 380–450 nm (688–789 THz frequency) Blue: 450–495 nm Green: 495–570 nm Yellow: 570–590 nm Orange: 590–620 nm Red…
Essentially, that equates to the colors the human eye can see.
A color spectrum of the light absorbed by the whole leaf shows that plants actually use a wider range of wavelengths, including green. The order of colors is red, orange, yellow, green, blue, indigo, and violet. CFLs and LEDs are available in warm colors (low k) to match the yellowish light of incandescent bulbs, but you can also choose cooler colors (high k) with whiter or bluer light. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Different Colors Do Different Things
Light in these colours can be added together to make the secondary colours magenta, cyan and yellow.
In reality, there are seven colors in the color spectrum with the addition of indigo between blue and violet. The visible spectrum is always the same for a rainbow or the separated light from a prism.
There are three primary colours in light: red, green and blue.
The most prominently apparent ones are violet, blue, green, yellow, orange and red. It is true that blue and red are important and represent most of the light used by plants, but other colors, including green and yellow are also used for photosynthesis.
In the visible spectrum of light, the color of the light depends on the frequency. What is Kelvin or The Kelvin Scale? Light color, or color temperature, is measured using the Kelvin scale. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10 -7 m, which is red).
